Materials Data on LaMg6Si by Materials Project
Abstract
Mg6LaSi crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 1-coordinate geometry to four Mg and one Si atom. There are two shorter (3.03 Å) and two longer (3.06 Å) Mg–Mg bond lengths. The Mg–Si bond length is 2.94 Å. In the second Mg site, Mg is bonded in a 2-coordinate geometry to six Mg, two equivalent La, and two equivalent Si atoms. There are a spread of Mg–Mg bond distances ranging from 2.94–3.21 Å. Both Mg–La bond lengths are 3.32 Å. Both Mg–Si bond lengths are 2.95 Å. In the third Mg site, Mg is bonded in a 10-coordinate geometry to eight Mg and two equivalent La atoms. Both Mg–Mg bond lengths are 3.13 Å. Both Mg–La bond lengths are 3.30 Å. In the fourth Mg site, Mg is bonded in a 2-coordinate geometry to four Mg and two equivalent Si atoms. Both Mg–Si bond lengths are 3.23 Å. La is bonded in a 2-coordinate geometry to six Mg and two equivalent Si atoms. Both La–Si bond lengths are 3.10 Å. Si is bonded in a 10-coordinate geometry to eight Mgmore »
